| Abstract: | The protection and switch procedure of WDM ring network configured as 1:1 protection mode is analyzed in detail by using the Logical Equivalent Scheme.Due to the analysis of the protection time of WDM ring network cooperating by the signaling system (such as APS),we derive the formula expressing its protection time.Accompanying the analysis of several factors affecting the protection time in detail,some useful optimization ideas are concluded.Finally,the sequence of time for protection process in the WDM network and one practial example by using typical parameter value are shown in our paper. |
